Ooops, linux 2.6.1

[Stian Jordet]

I don't know if anyone gets anything out of this. I tried running it
through ksymoops, but got just weird results.

Hope someone sees what's going on here.

Best regards,
Stian
ksymoops 2.4.5 on i686 2.6.1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.1/ (default)
     -m /boot/System.map-2.6.1 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
